The system fans use the motherboard fan speed control,
which consists of three states: Off, Normal speed, and
High speed. In Normal speed mode, the system fans run
at normal speed until the thermal sensor senses the tem-
perature exceeds the High speed fan threshold tempera-
ture. The system fans then run at High speed when the
temperature threshold is exceeded. You can set the fan
threshold temperature in the PC Health section of the
CMOS Setup Utility. You can set the threshold to 40°C to
force continuous operation of the system fans in high-
speed mode in the S0 and S1 sleep states.
More Information: Please see the PC Health Status sec-
tion of “Configuring the CMOS Setup Utility” in Chapter
5 for information.
WOL: Wake On LAN Connector J75
Function: A connector for the lead from a Network Inter-
face Card that supports the Wake On LAN feature.
Description: This feature enables the system to “wake
up” from Suspend mode when it receives a signal over a
LAN it is connected to. It works with the optional onboard
LAN port and will also work with an additional PCI NIC
that supports this feature by connecting the card to the
WOL connector on the motherboard.
The motherboard supports Wake on LAN through the
PCI bus PME# signal and the onboard Intel 82550 LAN
controller. This signal will wake up the computer only
when it is plugged into an AC power source and the sys-
tem is in a supported sleep state.
More Information: Please see the Power Management
Setup section of “Configuring the CMOS Setup Utility”
in Chapter 5 for information.
Fan power connectors
(orientation varies)
Cooling Fan Connectors:
The cooling fan power
connectors all use the
same 3-pin connector. The
System Fan connectors are
speed controlled, the CPU
Fan connector is not.
Wake On LAN Connector:
This connector is for an
additional NIC. The op-
tional onboard LAN port
supports WOL without us-
ing this connector.
